انعكاسات التغيرات المناخية على الوضع الجيمورفولوجي والهايدرولوجي في وادي البوطعمة

Abstract

The research aims to apply certain statistical equations specific to watershed basins and study their morphometric characteristics, both areal and shape-related. In addition, it analyzes the drainage network characteristics of the basin, based on the analysis of the Digital Elevation Model (DEM) of the Al-Buṭa’mah Valley basin, with a resolution of up to 14 meters. The study also highlights some modern hydrological equations such as lag time and time of concentration, and it investigates terrain characteristics and slope features through contour lines.

Morphoclimatic studies are among the most important branches in physical geography. The study of watershed basins has long occupied researchers and attracted the attention of geographers, who have established specific laws to understand the natural resources contained within these basins—such as water and other natural components—which can be utilized or mitigated against during flood seasons. The landform determines land use in all its natural and human aspects. Therefore, it is necessary to study it in detail. Moreover, studying landforms and the factors that led to their formation—whether internal or external—is essential, as the Earth’s surface is not static but rather constantly changing depending on the conditions affecting that part of the land and the hardness and types of rocks forming the region.
